The average squared distance of the observations from their mean

Variance

100

Displays the counts or percents of categories in a categorical variable through differing heights of bars

100

Tells you what values a variable takes and how often it takes these values

Distribution

When specific values of one variable tend to occur in common with specific values of another

Association

200

A measure of center, also called the average
